React's JSX uses large, lowercase conventions to differentiate the classes and HTML tags of local components. Renders the local react component requires a label name that starts with an uppercase letter, which renders the HTML tag with the name of a label that begins with lowercase letters Attention: Because JSX is JavaScript, some identifiers class are like and for are not recommended as XML attribute names.

However, in some cases, we do not want to pass through the parent component's props property one level down, and we want to get the value in the props of the parent component of the upper n level directly in a sub-component. 1. In general, through the props of the value of

React-router provides, props for setting a specific style on a Link component whose path matches our current route. Activestyle allows for a inline style while activeclassname allows for a class defined in an external stylesheet.const Links = () =nav> LinkActivestyle={{color:' Green '} to="/">HomeLink> LinkActivestyle={{color:' Green '} to= "/about">AboutLink> LinkActiveclassname= "Active" to= "/contact">ContactLink> nav>;.

React ' s inline styles allow the components of stand on their own by not requiring any external CSS. However HTML's style attributes don ' t support pseudo selectors like and :hover :active . By using Radium to listen to mouse events we can restore :hover and :active selectors to inline styles.const {Render} == document.getElementById (' root '= Radium ({children}) + = { Return ( {children} = { ' #07d ', ' None ', 4, ' #fff ',

In this lesson, you'll learn how to extend styles from the one styled-component to another in a React app. This was helpful when you had a styled-components that was similar but differ in one or more CSs properties.Import styled from ' styled-components '= Styled.button ' background-color: #FF851B; Border-radius:5px; Color:white; Display:block; Font-weight:bold; Font-size:22px; PADDING:16PX 32px; Text-transform:uppercase; = styled (Button)'

React ' s abstraction over the DOM means that it's not always obvious how does dom-related things, like working with the HT ML Canvas API.When working with HTML Canvas, HiDPI displays like Apple's Retina display require a bit of extra coaxing, to make sure the Y look crisp and sharp. This lesson covers how to write a method that automatically scales we component for the user ' s displays.Happily, once it ' s written, you can forget all about the DPI o

What Is InfernoInferno can be seen as another streamlined, high-performance implementation of react. It is used in the same way as react, whether it is JSX syntax, component building, component life cycle, or with Redux or MOBX, routing control, etc., can be basically in accordance with the react way to develop, only a small difference. However, Inferno is design

React originally came from a Facebook-based advertising system project, where front-end development was a huge challenge in the implementation of the project, and the code became bloated and messy and difficult to maintain. So, they decided to throw away many so-called "best practices" and rethink the way the front-end interface was built, so there was react.React brings a lot of pioneering ideas to build the front-end interface, although one of the m

Original address: Http://www.csdn.net/article/2015-08-04/2825370-reactIn the 2004, it was a milestone year for the front-end community. Gmail turned out to be a native app-level experience based on front-end rendering that boosted the time and touched the user's G-spot relative to the previous service-side rendering of the Web page. Since then, the front-end rendering site has been the direction that countless developers are chasing.To better develop front-end rendering of "native-level" sites,

The choice of Angular 2 and react is really just a style preference. React is focused on rendering speed and can handle complex UI designs in client or native applications, while angular 2 is more development-wide. It can not only guide us to build our own applications, but also provide some expressive and reusable UI design mechanism.Reactjs Quick Review Reactjs is a set of JavaScript Web libraries built b

The most magical part of react is the virtual DOM, and its efficient diff algorithm. This allows us to "refresh" the entire page at any time without worrying about performance issues and "without scruple", by the virtual DOM to ensure that the actual DOM operation is performed only on the truly changing parts of the interface. React is transparent enough in this section, and in real-world development we don
